SPECIFICATION forming part of Letters Patent No. 360,380, dated March 29, 1887.

Application filed October ll, 1986. SerialNofilSfiSl. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANCIS M. EVERING- HAM, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Road-Scrapers, of which the following, taken in connection with the accompanying drawings, isa full,clear,and.

The invention consists in an improved con-- 1 struction and combination of the constituent parts of a road-scraper which possesses superior efficiency of operation and many advantages over other machines of its class, all as hereinafter more fully described, and specifically setforth in the claims.

In the annexed drawings, Figure 1 is aside elevation of my improved roadscraper. Fig. 2 is a vertical longitudinal section ofthe same. Fig. 3 is a top plan view, Fig. 4 a rear end view. Figs. 5 and 6 are enlarged vertical sections taken on linexw, Fig. 3, showing the mold-board respectively in its operative position and in its dumped position. Fig. 7 is an enlarged detail side View of the combined hinged and swiveled connection of the moldboard to its support, and Fig. 8 is a rear view of that part of the aforesaid connection which is attached directly to the mold-board.

Similar letters of reference indicate corresponding parts.

The carriage of the road-scraper consists, chiefly, of the front and rear axles, A A, wheels \V on said axles, the head-block A, pivoted on the forward axle by the king-bolt in the usual manner, and longitudinal stringers S S, secured at opposite ends to the headblock A and rear axle, A. Said stringers are tied together intermediate the two axles by cross-beams F F, firmly secured to the stringers, and central between said stringers is alongit-udinal beam, E, secured to the crossbeams F F. A drivers seat, G, is mounted on the forward portion of the carriage, and a platform, H, is suspended from the rear portion of the carriage for carrying the operator of the machine.

Across the top of the described carriage are placed two beams, G G, pivoted at their centers to the carriage at points at the center of the line of draft. Said beams are thus allowed to swing horizontally into different angles to the line of draft. They are made to move in unison, and are maintained parallel with each other by longitudinal bars D D,of equal length,

pivoted to the ends of said swinging beams.

By means of a suit-able clamp or clamps the swinging beams C O are retained in their desired position. in the form of longitudinal barsc c, pivoted to posts 0 c, secured to the forward ends of the stringers. Said bars lie across the top of the swinging beam 0, and are provided with notches c c at different points of the lengths of the bars, which notches are adapted to engage ribs or bars d d, secured to the top of the swinging beam.

These clamps are represented l To the rear or free end of each bar 0 is conform H. By raising the free end of the lever e the bar 0 is lifted to liberate the swinging beam when desired to shift the same into a different angle to the line of draft, and by depressing the said lever the bar 0 is drawn down onto the swinging beam. The rib d on said beam, entering one of the notches c" of the bar 0, serves to retain the swinging beam in its position. To the carriage is rigidly secured a downward-projecting ratchet, f, which the lever 6 engages, and is thereby retained in its depressed position.

To each end of the swinging beam 0 is connected a hanger, g, and on the two hangers are hinged, by their forward ends, two arms, B B, which are arranged at opposite sides of the machine and carry by their rear ends the mold-board or scraper proper, M. The hinged connections of the forward ends of the armsB B allow the rear endspf said arms to be raised and lowered, and their movements are in arcs, the chords of which arcs are more orless rearwardly inclined, and consequently'in raising the rear ends of the aforesaid arms the moldboard or scraper M is carried to a greater or less degree rearward, and thus enabled to easily free itself from the substances which have been gathered on the front thereof. I render the aforesaid movement of the arms B B adjustable, to vary the inclination of the arcs in which they move, by providing the hangers gg each with two or more holes at different points in the length thcre0f,and to the forward ends of the arms B B, I attach straps, each of which is provided 'with an eye for the reception of the pin or bolt by which the strap is hinged in one of the holes in the hanger 9. By shifting the pin or bolt from one to another of the holes in the hangerg the forward end of the arm B is raised or lowered, and the angle of inclination of the arc in which the rear end of the arm moves is varied aecord ingly. V

The attachment of the mold-board M to the arms B B, I make as follows: To the rear end of each ofsaid arms I attach a ri id pendent bracket, a, on which I swivel loii 'itudinally one of the leaves of a hinge, Z), arrjfnged with itsjoint horizontally and at or near the lower extremity of the bracket a. The axis of the swivel is at right angles to the joint of the hinge and inclined slightly rearward at its upper end. The other leaf of the hinge is pivoted axially at right angles to its place on a plate, h, attached to the back of the moldboard. The described combined, swiveled, hinged, and pivoted connection forms a universal joint, which allows the mold-board to stand at different angles to the line of draft and to be dumped with its top forward when desired, as illustiated'in Fig. 7 of the drawings. The shifting of the mold-board in its position in relation to the lineof draft causes the change of the position of the hinge on the mold-board, as represented in Fig. 8 of the drawings.

The rear ends of the arms B B are supported adjustably vertically by means of cranked shafts or rods 1' i, mounted in boxesjj on the swinging beam 0, and having the cranks 2" on their outer ends connected with the rear or free ends of'thebeamsB B by hangers or rods h h. The connection of the said rods with cranks t" is made adjustable by providing each of said parts with a series of holes at different points in the length thereof for the reception of the coupling-bolt. To theinner cranks, i, which constitute the manipulating levers, I connect suitable pawls, Z Z, adapted to engage toothed sectors m m, secured to the beam 0. By manipulating the said inner cranks, t', and their pawls II, the operator, standing on the platform H, is enabled to raise and lower the rear ends of the arms B B and lock them in the requisite position to cause the mold-board to scrape the road to the desired depth, and also unlock said arms and raise them with the mold-board when desired to dump the latter, as hereinafter described.

The means for dumping the mold-board and for restoring it to its operative position con- The other leaf of the hinge is provided with an eye, by which it is connected to the guidepost a and adapted to slide vertically thereon. To the upper end of the leaf, which is pivoted on the m old-board and proj ects above the same, is connected a latch, 0, the free end of which is extended rearward, so as to be easily accessible by the operator standing on the platform H. Said latch is provided with notches 0, by which it engages a pin, 0", or other suitable catch projecting from the sides of the leaf, which slides on the guide-post a.

The dumping of the mold-board is effected by first lifting the mold-board by raising the lever or crank i of the rod 2, and then raising the rear end of the latch 0, so as to liberate it from the pin 0", and then pushing the latch forward, as represented in Fig. 6 of the drawings. The 1nold-board is restored to its operative or normal position by drawing back the latch 0 and retainingit by entering thcpin 0 into the notch o, and then lowering the mold-board by lowering the free end of the lever 17.

In order to transmit the draft directly to the moldsboard-supportingarnis B B, I employ a draft-link, l, arranged movable longitudinally across the forward axle, A, and independently thereof, preferably extended through apertures in the head-block A. With the rear end of the said draft-link-I connect a pulley-block, N, by means of a yoke, L, which rises from opposite ends of the link and is extended across the top of the head block A, the pulley-block N being hung on the rear upright portion of the yoke and adapted to slide vertically thereomfor the purpose hereinafter explained. Around the pulley of the pulleyblock N passes a draft-chain, 0', which by either rods or extension of the chain is connected to the rear ends of the arms B B.. From apoint back of the rear end of the draft-link I rises, toward opposite sides of the carriage and forward over the axle A and across in front of the headblock A, guides t t, upon which the pulley-block N slides when the forward axle is cramped or turned on the king-bolt. Said pulley-block and adjacent portion of the draftchain are thereby raised clear from the wheels IV To relieve the horses fro m jars and the draft connection from excessive strain I interpose between the'whifiietree and draft-connections a spring-coupling, u, of the form of a sleeve, having its forward end adapted for the attachment of the whiffletree and its rear end pro vided with a rigid cap,whieh is perforated/and has extending through it a red, the outer end of which is connected to the draft-link I, and the inner end has connected to it a nut, and

between this nut and the cap on the rear end of the sleeve is a spiral spring surrounding the rod.
